Understanding Accessory Dwelling Units (ADUs)

- Attached ADUs: These units are added onto the existing primary house.
- Conversion ADUs: These involve converting an existing part of the primary house, like a garage or basement, into an ADU.
- Property Value: Well-constructed and aesthetically pleasing ADUs can increase your property value.
- Flexibility: ADUs can be used for various purposes, such as a home office, gym, or guest house.
